No it doesn't.
And no to your 2nd question. Why add it unless you are categorizing all those of Polish decent as dumb? Why would race factor into their intellect? It shouldn't and that's why it's racist.
dont be a cracker
Well, the term "racist" means a belief in hierarchies of the races. That racial group A is superior to racial group B. You can be racist and never use a racist term, it's a mindset. In fact, you can be racist and never be hateful. Someone might believe that people of a racial origin are inferior to people of another origin but not dislike the inferior group of people. Similar to how we all like our pets but we don't consider them the equals of humanity.
By contrast, bigotry is when you look down on one race as a group. It means more than just thinking one group is superior, it's going so far as to actually dislike another group entirely (usually based on stereotypes but sometimes other reasons)
You can simply look up the 2 terms in any dictionary. Racism and bigotry center around beliefs and actions towards the group as a whole, not the individual.
sure, if you are using a word to stereotype an entire race, that is pretty clearly racist. That said, who cares. We dont have the history of being oppressed, so racist words dont affect white people as strongly.
I guess we'll just have to agree to disagree . . . people can say "dumb redneck" "dumb Okies" "drunk Indians", etc all they want. Just because I was born and live in Oklahoma and am part Indian doesn't mean I automatically jump to the conclusion that whoever said those things thinks every redneck is dumb, etc.
Heck, when I hear about certain stories on the news I have been known to say those exact things . . .
what would a person have to do to be racist?
